Membrane Processes: Properties, Advantages, and Limitations

This lecture covers the properties, advantages, and limitations of membrane processes in water treatment. Membranes act as absolute barriers, offering compact units with modular designs. The lecture discusses membrane fouling, scaling, filtration processes, operation methods, and the removal of micropollutants. It also explores polymers, membrane cleaning, and submerged membranes. Definitions related to membrane processes, retention/rejection, and flux through membranes are explained. The lecture delves into factors affecting micropollutant removal, rejection by reverse osmosis, and the importance of multibarrier treatment. It concludes with insights on membrane technology in drinking water treatment and process combinations for water treatment.
